Title: Phase shifter
Inventor: KAWAI KIYOYUKI
IPC: H03H11/16
Filed: 1982-01-13
Abstract: PURPOSE:To obtain a phase shifter which is free from the deterioration of characteristics at a high band, by generating the in-phase component of an input signal from a buffer amplifier of gain 1 and the adverse phase component from a phase inverting amplifier consisting of a negative feedback amplifier which sets the gain by the resistance ratio. CONSTITUTION:An input signal given from a terminal 31 is fed to a buffer amplifier 32 of gain 1 having sufficiently high impedance and sufficiently low output impedance, respectively. A part of the output of the amplifier 32 is fed to a phase inverting amplifier 33 consisting of a negative feedback amplifier to which the gain is set by the ratio between resistances 34 and 35. A resistance 36 which decides the phase shift characteristics and an end of a capacitor 37 are connected to the output terminal of the amplifiers 32 and 33, respectively. In such constitution, the output impedance can be reduced satisfactorily for the amplifier 33. This eliminates the reduction of amplitude at a high band due to the capaciter 37 or the parasitic capacity Cs. Thus the frequency characteristics can be greatly improved. In addition, the amplitude of the adverse phase component receives no effect of variance of current amplification factor of a transistor since said amplitude is decided by the ratio between resistances 34 and 35.
